Lift bar must be vertical to lift
load.
Interpreting the Lift Light
Never lift load unless
lift light is illuminated,
because premature lifting
could result in load release
and personal injury.
When the vacuum lifter is ready to lift the
Maximum Load Capacity, the vacuum lift
light turns
on
automatically and the vacuum
pump turns
off
temporarily, to conserve battery
energy.
Watching Vacuum Indicators
1A
Watch the vacuum lift light and both vacuum
gauges throughout the entire lift (fig. 1A).
Make sure all vacuum indicators
remain completely visible.
The vacuum pump turns on and off to overcome
any leakage. However, if the leak rate is greater
than normal, the notification buzzer chirps and
the LCD screen displays the message “Vacuum
decrease on circuit #”, along with a diagnostic
code (see “I
page 36).

Such leaks can cause the battery to be
discharged more quickly.
If the vacuum pump is unable to overcome leakage
, the notification buzzer sounds
continuously, the lift light turns off, and the LCD screen displays the message “INSUFFICIENT
VACUUM!”, along with a diagnostic code (see “I
this happens:
1..... Automatic leak detection is
not
a substitute for performing the “Vacuum Test” on page 30, required by the “I
and “T
” on page 29. Sensitivity of leak detection can be adjusted (see “INTELLI-GRIP® OPERATOR MENUS” in
SERVICE MANUAL
).
